How Jake Peacock Competes in the Art of Eight Limbs Without an Arm

Muay Thai, often called the “Art of Eight Limbs,” is a combat sport that demands the use of fists, elbows, knees, and shins—four pairs of striking weapons that, when combined, create one of the most complete and devastating martial arts in the world. But what happens when a fighter steps into the ring without one of those limbs?

Enter Jake Peacock.

Born without a right hand and forearm, Jake Peacock is redefining what it means to be a Muay Thai fighter. Not by making excuses or asking for exceptions—but by showing that the essence of Muay Thai lies not in what you have, but in how you use it.

Jake Peacock now competes on the global and leading Muay Thai promotion, One Championship.

Born Different, Fighting the Same

Jake Peacock didn’t choose his challenge, but he chose to fight. He was born and raised in London, England. He is the son of former Premier League midfielder Gavin Peacock, who played for clubs like Chelsea and Newcastle United before becoming a pastor in Canada. Jake was born with a congenital amputation of his right forearm due to amniotic band syndrome. At age 14, his family relocated to Calgary, Alberta, Canada, where he continued his martial arts journey.

Despite the obvious physical difference, he immersed himself in Muay Thai, refusing to let a perceived limitation define him. His training, mindset, and heart reflect the same warrior spirit found in every elite Nak Muay.

Competing in a sport that hinges on symmetry, balance, and the use of all limbs, Peacock has had to evolve his game. He fights with one full arm—but that’s never been a crutch. It’s become a catalyst for innovation.

As of now, Jake Peacock competes in the ONE Championship and is 2-0 in the promotion.

Turning Adaptation into Advantage

Jake doesn’t just “make do” with one arm—he’s crafted a fighting style that weaponizes his entire body differently. Here’s how:

Southpaw Advantage: Fighting primarily in a southpaw stance, Jake’s powerful left hand becomes the primary striking tool. He sets traps with it, using angles and timing to beat opponents who underestimate him.

Enhanced Kicking Game: Without a right hand to jab or cross, he relies heavily on explosive kicks—especially from his dominant left leg. His footwork and kicks compensate for the missing punches, often catching opponents off-guard.

Clinch Mastery: Jake has adapted clinch techniques to work with one arm, using his body, head position, and leverage to control opponents without needing a symmetrical grip.

Unpredictable Movement: Fighters are often trained to read standard combinations—jab, cross, hook. Jake disrupts that rhythm. His unique movement and angles make it difficult for opponents to predict what’s coming.

More than anything, Jake Peacock uses mindset as his deadliest weapon. He doesn’t fight to prove anything. He fights because this is who he is.

A Statement, Not a Story

What makes Jake Peacock stand out is not just his ability to compete, but his ability to win—and decisively. With an impressive professional record and highlight-reel knockouts, he isn’t a novelty in the sport; he’s a threat.

His presence in the ring challenges more than his opponents. It challenges assumptions. It shows young athletes with disabilities—or anyone facing obstacles—that you can not only participate in your passion, you can dominate it.

Jake doesn’t ask to be seen as an inspiration. He asks to be seen as a fighter. And that’s exactly what he is.
